We are satisfied except for screw.
It arrived today on September 8, 2018. The first impression is light anyway! ! Because it is quite rugged and a big clock, I was worried that my arms would get tired because of the heavy weights, but it seems to be dreadful. Not only the impact but also the moon data and tide graph, the radio wave for waterproofing, and the price is reasonable for a fairly high performance model among tough solar and G-shock. It would be a big plus for me who are fishing in the sea to feel the time of the sea visually. By the way, all of the four decorative screws that are often mentioned are yuruyuru. Work is sweet.

ビス以外は満足。

本日2018年9月8日に届きました。第一印象はとにかく軽い!!かなりゴツくてデカイ時計なので、重みもズッシリあって腕が疲れるのかなと心配していましたが、杞憂にすみそうです。対衝撃はもちろん、ムーンデータとタイドグラフ、防水に電波、タフソーラーとGショックの中でもかなり高機能なモデルな割に値段も手頃。海釣りをする自分にとって、海の時合いを視覚的に感じられるのは大きなプラスとなりそうです。因みに皆さんよく言われている飾りビスは4つともユルユルです。仕事が甘い。

Because it ’s rugged
I bought a radio watch for the first time, it was accompanied by a certificate and instructions, whether it was the four screws on the watch or the screen. I will use it.

ゴツいので

初めて電波時計購入しました、証明書と説明書が付いていました、時計にある4本のビスどうかなと画面の件どうかなですね。使っていこうと思います。

Bali is cool!
It ’s really cool! It's just a decorative screw, but keep your face down! If you wrap it around the cuffs of your shirt, you ’re cool! Just tilting G in the dark, it's pretty easy to see the display glowing blue and checking the time. Four decorative screws that tighten the face. It looks like it ’s going to fall, but I stopped it with a small amount of bond. I think the equipment that I rarely use is a design, isn't it cool?

バリかっこ良い!

ゴツい、カッコイイ!あくまでも飾りビスだが顔つきを締めとる!シャツの袖口に巻けばバリかっこ良か!暗所でGを傾けるだけでディスプレイが青く光って時刻を確認出来るのはなかなか使える。顔つきを締める4本の飾りビスがグラグラ。落ちそうじゃけん、微量のボンドで止めました。殆ど使わない装備もまぁデザイン何だと思って、カッコイイけん良いんでねぇの?

Don't buy it in appearance
I was attracted by the design of white letters on the black background (actually gray), but it was difficult to see. It is difficult to read without looking at the dial vertically. The normal digital type with black letters is definitely better in recognition. Other than that, it ’s perfect. As expected, Casio. (Individual impression)

見た目で買ってはダメ

黒地に白抜き文字(実際はグレー)のデザインに惹かれて購入しましたが、見にくい。垂直に文字盤を見ないと読み取りにくいです。黒文字のノーマルなデジタルタイプのほうが認識性は絶対に優れています。それ以外は特に申し分ありません。さすがカシオ。(個人の感想です)

I originally bought it for Sabage, but the design is not bad and I usually use it regularly. Is it a little bigger in the G-Shock? There is no complaint because I like it.

とても気に入っています

元々サバゲーのために買ったのですが、デザインも悪くないですし普段も愛用しています。Gショックの中では少し大きめでしょうか。そこが気に入っていますので文句無しです。

I bought something with a good presence, but I like it as I expected. It was value for the existence like G-Shock, but it was satisfactory with radio waves, solar, so-called maintenance without any so-called maintenance. I was prepared, but it was hard to see the reversal. I don't care because it is a reversal that I chose.

気に入りました

存在感のあるものが良くて購入しましたが、思っていた通りで気に入っています。Gショックらしい存在のわりにお値打ちですよ電波、ソーラー、いわゆるメンテ無しで正確でなお見た目もいいと満足いくものでした。覚悟はしてましたが、反転は見づらいです。そこはあえて選んだ反転なので気にしていません。

It ’s a little big but it ’s good to have a presence. Tough solar so you don't have to worry about running out of batteries. Since the time is also a radio wave, it automatically adjusts. If you are wondering what to buy, this is for the time being.

何を買ったらいいか迷ったら コレ!

やや大きいですが 存在感があって良いです。タフソーラーなので電池切れの心配なし。時間も電波ですので自動で合わせてくれる。何を買ったらいいか迷ったらとりあえずコレ。

Really tough
We purchase for hot summer under the midsummer, hot spring, outdoor. He / she ticks away the exact time without any madness in any situation. I usually use Rolex and Citizen habitually, but I think that it is a gear that never loses by having one.

本当にタフ

真夏の炎天下や温泉、アウトドア用に購入。どんな状況でも一切狂うことなく淡々と正確な時間を刻んでくれています。普段はロレックスやシチズンを愛用していますが、絶対にひとつ持っておいて損はないギアだと思います。

The atmosphere is great
It ’s rugged. It is the best watch for those who like rugged watches and want durability and reliability. As for visibility, priority is given to the atmosphere, so visibility is not good, but if you do not wear sunglasses, it is a level without problems.

雰囲気最高

ゴツいです。ゴツい時計が好きで、耐久性、信頼性を求める人には最高の時計です。視認性について、雰囲気を優先してますので視認性は良くはないですが、サングラスをかけてなければ問題の無い水準です。

-Wear the next day after ordering. Delivery time is early and is satisfied. Although the actual product was also in the review of the other person, the decorative screws at the four corners have no play and there is no problem! The G-Shock I used so far was solar, but it was not radio waves, so I was dissatisfied with the time being crazy. In addition, there was thing that liquid crystal display was hard to see, but did not feel so.

ゴツイ感じがGood!

・注文の翌日には着。納期が早くて満足です。現物も他の方のレビューにありましたが四隅の飾りネジはガタもなく問題なし!これまで使っていたGショックはソーラーでしたが電波ではなかったので時間が狂うのが不満だったので今回はソーラー電波にしたので満足です。又、液晶表示が見辛いとの物もありましたがそうは感じませんでした。
